According to Apollonius of Rhodes, the only person
According to Apollonius of Rhodes, the only person who was immune to the effects of this place was a son of Hermes of Eupolemia named Aethalides, who was the herald of the Argonauts. In Valerius Flaccus's Argonatuica, Medea uses a bough from this place to incapacitate the guardian of the Golden Fleece. This place was allegedly surrounded by its namesake poppies and was located near the mountain Cimmeria, the home of Hypnos. Just beyond this place was the "second" Elysium, a resting place for souls that the Fates had decided to reincarnate. According to Plato, the effects of this place were only felt if one consumed more than a measured amount. In order to be reincarnated, these souls were required to drink the waters of this place so that they would not remember their prior life. For ten points, name this river of forgetfulness in the underworld.
